The face of a tent is shaped like a triangle with an area of Fifteen point one two five feet squared. The area of the triangle is represented by the formula A equals one half b times h. The height of the tent is 5.5 feet. How wide is the base of the tent?


5.5 feet


6.0 feet


6.5 feet


7.0 feet

Verified Answer :

The answer is 5.5 feet.

15.125= 1/2 b h

15.125= 1/2 b (5.5)

2(15.125)= 2 (1/2 b (5.5))

30.25= b 11

30.25/11= b 11/11

2.75 = b

You have to check it so when you plug the solved variable back in

15.125= 1/2 (2.75) (5.5)

15.125=  7.5625

So because the original b variable does not equal to the area of the triangle, you multiply the b variable by two to get 5.5 and when you plug that in, you get 15.125.
